Answer 1

Of course you can.

You must output the Stream Result type from your Action, and specify a parametric contentType, for example:

Struts.xml

  ${yourContentType}
  inputStream
  attachment;filename="${yourFileName}"
  1024

Action

@Getter @Setter private InputStream inputStream;
@Getter private String yourContentType;
@Getter private String yourFileName;

public String execute() throws Exception {

   yourContentType = "audio/mpeg";
   yourFileName = "yourStuff.mp3";
   byte[] yourContent = loadTheContentInSomeWay();

   setInputStream(new ByteArrayInputStream(yourContent));        

   return SUCCESS;
}

You can parameterize the contentDisposition part to specify when a file must be opened as attachment (ask for download) or inline (open in browser) according to your needs.
